The Vallée de la Marne, which is shown on the map in verdant green, features terroirs with cooler climates due to the natural topography of an east-west orientated valley where shade and sun exposure are determined by the time of day. The denser clay-rich soils favour the meunier vines which account for about 70% of all its champagne production. Meunier grapes are a hardy variety, tolerant of the area’s frost-prone conditions and heavy topsoil. The diverse champagnes of the Vallée de la Marne blend a foundation of the hardy meunier with the more temperamental pinot noir. The result is a compelling combination of spice and herbal savoury flavours.
It is one of the largest regions of Champagne and includes the sub-regions of Grande Vallée de la Marne; Rive Droite and Rive Gauche (ie the right bank and left bank of the Marne river); and Côteaux Sud d’Épernay.
